To all whom it may concern;

Be it known that I, LEMON M. REED, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a new and useful Mixing Apparatus for Making CementitiousProducts, of which the following is a specification.

This invention relates to improvements'in distributed over an open boxor receptacle for receiving the resulting cementitious product.

Another object is to render said apparatus highly eflicient and reliablein the performance of its functions and simple and durable inconstruction.

I Another object is to have said apparatus comprise simple and eflicientmeans for wet-- ting or moistening the hereinbefore mentioned mixtureduring its passage and in proximity to the aforesaid receptacle.

With these objects in view, and to attain any other object hereinafterappearing, this invention consists in certain features of construction,and combinations and relative arrangements of parts, hereinafterdescribed in this specification, pointed out in the claims, andillustrated in the accompanying drawings. r p In said drawings, Figure 1is a vertical longitudinal section of apparatus embodying myinvention.Fig. 2 is a vertical transverse section taken along the line 2-2, Fig.1, looking in the direction indicated by the arrow. Fig. 3 is avertical'transverse section taken along the line 3+3, Fig. 1, look ingin the direction indicated by the arrow. Fig. 3 is drawn on a largerscale thanthe preceding figures, and portions are broken away in Fig. 3to reduce the size'of the drawmg.

' eferring to Fig. 1 of said drawings, 11 and 12indicate two hoppers for"receiving drysand and dry hydraulic cement respecti-ve'ly .Said hoppersare adapted to dis charge downwardly and arranged side by side andsupported from and rendered rigid with stationary framework 13 in anyapproved manner.

resting on the floor 15. Two laterally spaced substantially horizontaland substantlally parallel rotary conveyers 17 and 18 are arranged underthe outlet of the different hoppers 11 and 12 respectively. The

- conveyers 17 and 18 are operatively mounted on correspondinglyarranged shafts 19 and 21 respectively which are supported from theframework 13 and operated in any approved manner, and eachconveyer hasperipheral chambers 20 spaced eircumferentially of the conveyer andarranged to communicats with and receive material from the outlet of thesuperimposed hopper during the rotation of said conveyer. Said shaftsare of course rotated in the direction required to rotate the conveyers17 and 18 in the direo tion necessary to feed materials received fromthe hoppers into the space between the lower portions of the conveyers.Means for effecting the operation of said conveyers are too well knownin the art to require further description and illustration in thisspecific-ation. Adjacent each conveyer (see Fig. 1) isa guard whichextends from the outlet of the hopper arranged above said conveyerdownwardly circumferentially of the inner side of the upper portion ofand is arranged in close proximity to said conveyer. Each guard 28 isarranged and adapted to cover a chamber 20of the conveyercircumferentially of which said guard extends, and said chamber does notdischarge the contents thereof during the operation of the conveyeruntil the chamber has begun to movebelow the lower end of said guard.The cementconveyen 18 is shown as having twice as -many chambers 20asthe sand-conveyer 1'1, and each chamber of the sand-conveyer'is shownas having over twice the capacity of a chamber ofthe cement-conveyer,and the relative operation of said conveyers is such astofeed: cementand sand, 1n the desired proportion, into the space between thelowerportions of the conveyers. are located atthe outer side ofthe'dlf'ferent Two guards 24 conveyers respectively. Each-guard 24extends. from the outlet" of the adjacent hopper eircumferentiallyoftheadjacent conveyer and isarranged and adapted to cover a chamber 120of said. conveyerxllpon the Said framework is shown fioor'l5, below theconveyers 17 and 18, is

an open box or receptacle 25, and said conveyers are arranged farenoughabove said receptacle to permit the arrangement, be tween saidreceptacle and said conveyers, of

apparatus en'iployed in mixing the sand and' cement during the passageof said materials from sa-id conveyers to said receptacle."

26 which is open at its upper and lower ends and arranged between thereceptacle 25-and the conveyers l7 and 18. Preferably said casing isenlarged in thickness, as at 27 at its lower end and suspended byupright links 28 from brackets or members 29 which are rigidwith andproject fromthe hoppers 11' and 12 and are consequently rigid with theframework 13. 2 At each side of said casing are two uprightlinks 28which are pivoted at their lower ends, as at 30 to said casing: andpivoted at their upper'ends, as at 31', to the link-supporting members29. Eachlink 28at each side of the casing 26 is arranged opposite a.corresponding llnk at theopposite side of the casing, as shown in Fig.2.- The pivotal connections between the casing 26 and the links 28 andthe pivotal members 31 connecting said link to the liiiltsiipp ortingmembers 29 are parallel with the conveyers 17 and 18. The casing 26 istherefore shown arranged and supported as required to render'it capableof being reciprocated in a substantially horizontal plane. A crank-shaft32 is supported from the top; portion of the framework 1 3 at on'e endof said framework, and saidshaft is parallel with the conveyers 17 and18, and preferably a link 28 at eachside of the eas ing 26 isoperatively connected by a pit-man 33 with a crank 3t 01": said shaftwhich is rotated in'any approved manner, duringthe operation-of theconveyers, to effect a rapid reciprocation of said casing. Theframework-13 is provided with a pair ofsubstantially horizontal andsubstantially parallel laterally spaced bars 36 whichare arrangedinternally of thecasing 26 and extend longitudii'ially of the travel ofsaid casing. The

-bars36 are supported'from and rigid with bracl'rets with -which the topportionof the framework 13 is provided. Said bars aretspaced downwardlyfrom the conveyers 17'and18'and upwardly fromth'e lower end of thecasing '26, and the relative'arrange- 'ment of theparts is such as to;permit moveinent'ofvsai'd casingl longitudinally, of said barsinopposite directions alternately by the hereinbefore described operativeconnection of: said casing-with the-'crank-shaft 32. The

brackets 37 at each end ofwthe pair of bars 36 are=tied together-by bars38 so as torrenden thecbars 36 adequately rigid. The bars 36areprovided: with a row of four inclined metal: plates arranged thereoninter- "wardly. By the construction hereinbefore ranged transversely: ofsaid row.

nally of the casing 26, and said plates are rigid with and spaced andextend longitudinally of said-bars. Adjacentplates39 slope downwardly inthe direction of opposite ends respectively of the bars 36 and arearranged to receive materials to be supplied from above and to be mixedduring the reciprocation of said casing, andthe two inner plates of saidrow of plates diverge updescribed it will be observed that each outerplate and the adjacent inner plate of said row of platesconvergeupwardly and that the bars 36 and the said platesare supportedindependently of the casing 26 and are stationary, being rigid with theframe-Work 13. Means wherebythe materials delivered by the conveyers 17and 18 to the space between the lower portions of said conveyers areconducted or fed over and to and between the stationary plates 39comprise two downwardly diverging inclined metal plates 40 supportedfrom the casing 26. The end walls of said casing preferably do notextend upwardly as far as the bars 36, wherea the side walls of saidcasing ex teud above said bars-and above the plates 40. The plates l0are arranged over the bars 36 and meet attheir upperends and haveflanges 11- secured to the casing. 2 in any approved manner. The plates39 of the bars 36 are therefore arranged toreceive materials from theplates l-0 duringthe reciprocation or actuation of the casing 26longitudinally of said bars; Each plateO in the central position of thecasing 26 (see Fig. 1) has itsupper end under the central portion of thespace between the lower portions ofthe-conveyers 17 and 18 andover thespace between the lower ends of the inner upwardly diverging plates 39,and has its lower end in posi'tion over thespace between two adjacentupwardly converging plates 39. 'Tlierelative arrangen'ient oi the partsis such that the stationary plates 39 are arranged wholly internally ofthe casing 26 in anyposition of theca-sing. Each plate oi therow ofplates 39 has a flange 42 which projects substantially verticallydownwardly from'the upper end of said plate and is ar- The flanges 412-of adjacent upwardly converging 7 plates- 39 are helpful in guiding:materials verticallydowmvardly through the space between said flanges.The plates 39 have '120 flanges 13' securedoto' the casing'26 in anyapproved manner. Said casing: is: provided internally and below thestationaryi plates 39Kwith' meansfor retarding. the movement oimaterials from said plates and from the spaces between said plates tothe lower end=of thecasing and for further mining and distributingsa idmaterials during said movement, and-said means comprise threevertically: spaced substantia y p e 3 0;

of inclined metal plates 45 arranged internally of and supported fromand movable with the casing. The rows of plates 45 are arrangedlongitudinally of the bars 36, and adjacent plates of each row of plates45 slope downwardly in'the direction of opposite ends respectively ofsaid row. Adj acent downwardly converging plates of each row of plates45 are; spaced attheir lower ends. Adjacent upwardly converging platesof the upper row of adjacent rows of plates 45 extend into closeproximity to each other and preferably meet at their upper ends and.

have their upper portions arranged over the space between the lower endsof two adjacent downwardly converging plates' of the lower row of saidadjacent rows of plates. Each of adjacent upwardly converging plate ofeach row of plates 45 is provided at its upper end with a substantiallyvertically upwardly projecting flange 46 extending transversely of saidrow. The plates 45 have flanges 47 secured to the casing 26 in anyapproved manner. The flanges 46 of adjacent upwardly converging platesof each row of plate 45 abut against each other and form a partition,and each partition thus formed at the top of the bottom row of plates 45is substantially in line vertically with a partition formed at the topof the top row of plates 45. Each partition formed by abutting flanges46 is helpful in efiecting a substantially equal distribution ofmaterials to the plates diverging downwardly from said partition.

Means for wetting 0r moistening the dry mixture of sand and hydrauliccement, upon the passage of said mixture from the plates of the bottomrow of plates 45, comprise perforated pipes 48. Preferably the casing 26is provided over the space between the lower ends of adjacent downwardlyconverging plates of the bottom row of plates 45 with a substantiallyhorizontal pipe 48 arranged transversely of said rowand supported by andmovable with the casing 26 and (See 3) provided at its bottom withperforations 49which are spaced at short intervals longi ftudinally ofthe-pipe and airangedto discharge downwardly into said space, and ob--pipe 53 having a valve 54 upon opening which water is supplied from saidsupply pipe through the branch-pipes 52, tubes 51 and pipes 50 to thepipes 48.
